The roster move is hardly a surprise as Bergesen -- who was optioned to Triple-A Norfolk on Saturday -- traveled with the team to New York on Monday and has been waiting to find out his status. Given Tuesday's rainout, the Orioles were able to skip Bergesen's turn in the rotation -- which would have been Wednesday -- and he is tentatively slated to make Sunday's start in Cleveland.

"I'm really just hoping to get back on track and hopefully prove that I am able to be part of the rotation and just contribute to this team," Bergesen said.

"It's been tough, but it's the hand that I was dealt and I'm just trying to make the most of it. Whatever they need me to do or whenever they need me, I'm just trying to prepare as much as possible."

Bergesen has pitched just one game so far this season, starting against the Detroit Tigers in lieu of Jeremy Guthrie, who was hospitalized with pneumonia and had his start pushed back. Bergesen allowed four runs (two earned) in 3 2/3 innings against Detroit and hasn't been able to establish a consistent throwing schedule. The 25-year-old Bergesen had a 5.82 ERA in six games this spring, and was hit with a line drive on his right forearm in the first inning of his final Grapefruit League start, forcing an early exit.

Asked how important it was for Bergesen to get on a regular schedule, Orioles manager Buck Showalter, who will use Bergesen if Wednesday's starter Chris Tillman has a rough start, didn't want to jinx things.

"Let's let that play out," Showalter said. "With the injuries and all the things that we've had creep up, it's not an ideal world. But there's an excuse around every corner if you want to take it."

If Bergesen is not needed on Wednesday he will prepare to start the series finale in Cleveland this weekend, and will presumably be able to get on schedule since the team needs five starters for their upcoming schedule.

Hardy is expected to be out a minimum of two weeks, and potentially three, according to Orioles president of baseball operations Andy MacPhail. The club will have to wait and see how Hardy's rehab goes. Showalter said Hardy has reported to extended Spring Training camp in Sarasota, Fla., and has been receiving treatment.
